Ciliwung River

The Ciliwung is a 119km long river in the northwestern region of Java where it flows through two provinces, West Java and the special region of Jakarta. The natural estuary of the Ciliwung River, known as the Kali Besar, was an important strategic point for trade in the precolonial and colonial periods and was instrumental in the founding of the port city of Jakarta, but has been lost from a reorganization of the watercourse of the rivers around the area into canals.
